function save() {
    document.getElementById(\"canvasimg\").style.border = \"2px solid\";

Answer 1

If you're using ctx.drawImage() function, you can do the following:

var img = loadImage('../yourimage.png', callback);

function loadImage(src, callback) {
    var img = new Image();

    img.onload = callback;
    img.setAttribute('crossorigin', 'anonymous'); // works for me

    img.src = src;

    return img;
}

And in your callback you can now use ctx.drawImage and export it using toDataURL
